I got New Dell Inspiron 14, which is a brand new laptop. It has an 11th Gen i5 CPU. So, it should be very fresh, with the latest drivers and design. After I used a week, I found its screen is flickering if that is not connected with the power adapter. That is strange. I am worrying that it is a hardware failure. I entered the BIOS and ran the diagnosis test. That is fine. Then I did some google searches. The older models got similar problems after the windows upgrades. The suggested solution is just running the drivers upgrade. However, this is a new laptop, which should be just coming out from the factory not long ago. Well, that is no harm to do a driver update. Then I upgraded all drivers and BIOS. Then that is the problem. Strange, I think that laptop should be already with the latest drivers, but actually, that is not.
